Alfresco 3.4.2 clustering : session replication

jnjp28

Hi,

i'm trying to mount a Alfresco + tomcat 6 clustering.

To configure clustering i did this

In web.xml i put the param "distribuable"

In my tomcat servers conf files i put this line :

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>‍

When i'm starting my tomcat nodes i have this warning :

org.apache.catalina.ha.tcp.SimpleTcpCluster
registerManager
WARNING: Manager [ org.apache.catalina.session.StandardManager@2fe6e305]
does not implement ClusterManager, addition to cluster has been aborted.

Then i try to authenticate in the first node. The authentication is OK
Then i stop the first node.
Then i do an action in web-client
Alfresco forward me to the login-page

The session replication doesn't work and i don't know why…

Can you help me?

Regards
